To all whom it may concern:

Be it known that'I, HUGH MoLAUGHLIN, a citizen of the United States, residing at Loami, in the-eou'nty-of Sangamon and State of Illinois, have invented a new and useful Nut-Lock, of which the following is a specification. i

This invention relates to nut and bolt locks, and has for an object to cheapen the construction and provide adevice of the class embodying new'and'improvedfeatui'es of convemence, simplicity, strength, and efiiciency.

A further object ofthe'-invention-is to,- rovide a bolt having its threadintersected y a longitudinal slot in' the bottomof which are formed sockets and bendable keyswith each a hook inserted in a socket and the free end bent, or to be bent, against the outer surface of and to hold the nu With these and other ends in view the invention consists in the improved construetion and novel arrangement and combination of parts, which will be hereinafter fully despribed, and particularly pointed out in the 0 mm.

. In the drawings, Figure 1 is a perspectiveview of a bolt embod 'ing the improved lock and showin one nut ocked'thereon. Fig. 2

. is a longitu al sectional view of'a-boltembodyingK the improved lock-andtshowing one nutloc ed and another nut in position for locking. Fig. 3 is a perspective view of the key before application;

Corresponding partsinthe several figures are indicated throughout by l similar charac ters of reference. 7

Inits referred embodiment the improved nut and olt lock forming the subject-matter of thisapplication comprises a bolt 10, of any approved size,"length, and form, provided with the screw-threads 11 in the usual manner. Longitudinally of the'holt are formed any approved number of ooves'12, here for clearness of illustration s own as only one,

and which number will under; ordinary circumstances in ordinary use he found sufficient. The groove 12 is'formed throughout the threaded portion of the bolt, and in they bottom ofthe rooveare formedspaced sockets, holes, or epressions13,,-the number of such sockets, as well asitheir size and the intervals therebetwe'eii, depending upon the size and length of thethreaded portion and the use to which the bolt is to be put.

in the groove is a key 14, proiportioned to be wholly contained therein an having at one end a hook or offset 1-5, proportioned to enter and be seatedin one of the sockets 13. Upon the threaded ortion is disposed a nut 16 of any usual an ordinary form, and the end 17 of the key opposite the hook iscapable of being bent without the groove and into binding contact with the outer end of and to hold the nut from a backward movement. a g

It will be understood that when the key is placed in'the groove and the hookwithin-the socket is free the nut is applied and that the hook is placed toward thehead of the bolt and at about the limit of movement of the nut. The nut is then'applied and screwed tight in the usual manner, after which the free end of the key is bent up, as shown, to bear against and engage the'outer surface of the 'nut.

It will be obvious that the groove and spaced sockets may be formed at the same.

time the bolt is forged and in the same operation and that the cost will not thereby be increased. Any usual and ordinary nut will be used, and the keys, being very simple and of non resilient wire, may be manufactured at an almost negligible-cost. e

If it is desire to remove the nut, the key is simply bent down a aininto the groove and l the nut removed in t e usual manner. The

keys can generally be used a great number of times, but if broken orlost may be replaced with a new one at practically'no expense, or in case of emergency a key may be made on the s ot from a small piece of wire, a nail,-or

It is to benotedthat the de ression's 13 are s aced apart. distances whic are less than the ength ofjthe'keys 14, so that it is always possible to place-a key in one of said depressions so that one end of the keycan be turned upwardand overlap th'e'nut. This'is true no matter what position the nut may as-.

sume on the threads.
